Creating home directory exports using substitution variables

Guidance to set up SMB exports for efficient home directories

Having many Windows users all concurrently accessing the same SMB export can lead to performance bottlenecks because Windows clients automatically open the root folder of an export when they connect. In a home directory environment, it is recommended that substitution variables be used when creating SMB exports for home directories. For example, home directory exports can be created by using the %U substitution variable that represents the user name on the mmsmb export add <export> <path with substitution variable> ” command ( mmsmb export add home /ibm/gpfs0/.../%U). For more information, see mmsmb command.
